Depends on the camera body. The K10D and K20D create DNGs with no compression at all, so they quickly fill up SD cards. So I shoot PEF (compressed) and convert to DNG on import (then nuke the PEFs). The K-5 and probably all more recent models (eg K30) create properly conformant DNGs, all nicely compressed. So if I had one I'd choose DNG. I'm not sure which camp the K-7 falls into. If you have an existing stable of PEFs, there may be a nice way in Lightroom to force it to reprocess them all and create DNGs from them. I'm not sure I'd bother myself. -- -bmw -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
